Military/Rescue - Troop Transport/Combat Boats


Specwar 20-foot troop transport/combat boat

The Patten Assault D560, D500 and D450 evolved from over 60 years of designing inflatable life saving equipment and high-speed assault boats. The original stacked tube models, designated RB-12 and RB-15, were designed specifically for covert operations in 1958. "They" needed a boat that was more rigid than the single tube design, faster, with more interior space, that could fit into the same package and could be launched from a submarine escape trunk in the forward torpedo room.

From that development we bring you the Specwar D-series.

Deck Layout and Seating Arrangements

The craft can be outfitted for almost any type of infiltration/exfiltration scenarios. Seating arrangements can accommodate up to 12 personnel in the D560 and many other custom options are available on all models.

Coat Fabrics and Construction

All the materials used in this craft are made in the USA. The UV and chemical resistance of our coated fabrics surpasses any commercially available boat fabric. All seams are thermal bonded to insure superior air retention, strength and longevity. The base cloth is a 1050 denier woven polyester with a DuPont elvaloy copolymer. The finished weight is 40 oz/sq yd. Mechanical properties included under Fed Std 101 exceed 30 lbs/sq in of coating adhesion (in peel) and over 100 lbs puncture resistance.

Transom, Floor Boards and Keel

All are FRP composite. The transom and floor boards have a state-of-the-art foam core.
